Hi,everyone:I am new to bitcoin area and blockchain technology.I have been reading a lot of papers related to how to apply blockchain technology to some specific areas, for example, user authetication, health record or more.

I am wondering are they using bitcoin blockchain system if they apply blockchain technology? If yes, I will assume each of their implementation come with a bitcoin cost.If it is true, it would make me more confused, because for some paper, they apply block chain on the cloud in the area of user authentication. If we don't use blockchain, then we don't need to pay but since they use blockchain, I assume there is a fee for that(because miner get some reward, this reward must come from somewhere!!)

If no, what I mean is, if they are not using bitcoin blockchain sys, then they build up their own?? As what I know, all the benefits of [Suspicious link removed]es with "there are a number of miners compete with building a block", if they create their own blockchain, how can they make sure there are "enough" miners in their sys???

I would say, none of the paper mention about the incentives when they use blockchain technology, which makes me think they are kind of lack of applicability.

The only purpose is to ride the hype train and somehow get the term "blockchain" into the own project's name.Blockchain-based pizza delivery service? Who cares if anyone needs that, it's damn sexy ... NOT!

"Other" than what? I have not seen any high quality (!) financial platform that, for example, would have a stable feature for P2P lending. I can think of one at the moment, but to be honest, it still is under development so I cannot know how many others will implement the idea. So, P2P lending is a feature I yet want to see in work.

Blockchain Definition:A blockchain is a type of distributed ledger, comprised of unchangable, digitally recorded data in packages called blocks.These digitally recorded "blocks" of data is stored in a linear chain. Each block in the chain contains data (e.g. bitcoin transaction), is cryptographically hashed. The blocks of hashed data draw upon the previous-block (which came before it) in the chain, ensuring all data in the overall "blockchain" has not been tampered with and remains unchanged.
